SELF-SOAPING SHAVIhTG-BRUSH.

raeaoo'a will be capable of discharging a measured quantity thereof into the body of the brush head where it will quickly produce a shaving lather when the brush is applied in the ordinary manner. Y 1 p Another object of the invention is to provide such a brush with means for thoroughly protecting the powdered latherproducing material from the action of water in the ordinary use of the brush. a

With the above and other objects in view the invention consists in the self-soaping shaving brush as herein claimed and all equivalents.

Referring to the accompanying drawings in which likecharacters of reference indicate the same parts in different views:

Figure 1 is a central sectional view of a shaving brush constructed in accordance with this invention, the plunger being in its inner position ready for use; and

Fig. 2 is a similar view thereof w1th the plunger in its outer a charge of lather the feed barrel.

In these drawings 10 indicates the brush head which as here shown is bound within a sheet metal brush binding 11 having a central tubular feed barrel 12 communicating with the interior of a cylindrical storage chamber 13 which is threaded or otherwise secured to the brush binding 11. The brush binding 11 constitutes a closure for one end of the storage chamber 13, though the tubular barrel 12 therethrough permits of a discharge of the contents of the storage chamber into the interior of the brush head 10in regulated quantities as determined by the operation of a plunger 14. The plunger 14 is mounted to reciprocate within a tubular guide 15 of a removable screw cap 16 which is threaded on and'forms a closure for the other end ot'the storage chamber 13. lBfiy means of a ob 1? on the producing material to Specification of Letters Patent.

end of the plunger stem 1 1 the plunger may be moved from the position shown in Fig. l where its enlarged head 18 fits within the feed barrel 12 to the position shown in Fig. 2 where the plunger head is withdrawn entirely from the feed barrel 12 to permit a flow of the shaving powder from the stor age chamber into said feed barrel. The shoulder formed by the head of the plunger engages the end of the tubular guide 15 to limit the outward movements thereof, and the engagement of the knob 17 with the screwcap l6 limits its inward movements.

In operation the storage chamber forms a magazine in which the supply of shaving powder 19 is placed when the screw cap is removed. When it is desired to use the brush, it is dipped in water and then the plunger is withdrawn to admit the powder to the feed barrel and again depressed to force a charge of powder out of the feed.

barrel and into the brush proper, where it is in best position to be worked up into a lather on theface. The size of the feed barrel is such that there is no waste of shaving powder and only the necessary quantity for a shave is discharged'with tion of the plunger.

The end of the plunger head is preferably made slightly the feed barrel is preferably slightly flaring to facilitate the entry of the plunger in the feed barrel.

By means of this invention the shaving brush is made to provide a charge of soap or shaving powder within the brush head where it will readily be dissolved and worked into a lather by the movements of the brush. The discharge of the shaving powder into the interior of the brush head causes it to be retained by the brush head until it is completely dissolved and worked up into a lather, instead of being deposited in one place, as frequently happens where the powder is applied to the exterior of the brush head. The spread of the brush fibers effectively seals the end of that the powder does not have an unlimited flow when the plunger is raised. The feed barrel is of such a length as to continue through the binding of the brush head where the brush fibers are under compression and conduct the charge of powder to the portion of the brush where the brush fibers have considerable movement and are capable of work g t ll- T9 a la he Th s tapering and the end of l each operathe barrel so long barrel and the correspondingly long cooperating plunger head protect the shaving powder in the-storage chamber from the water in the brush and even though the brush is allowed to stand inwater thereis no danger of the powder becoming damp so as to interfere with the free movement when the plunger is withdrawn. The end of the plunger head passes beyond the end' of the feed barrel to prevent obstruction of the latter that might otherwise be formed by the powder becoming caked in the end I thereof. r
